Well, it's definitely not at its usual level and his timing is off. Querrey's unforced errors might save him.
I don't really blame them but it's so sickening to see the fans cheering for Querrey as if this would have been competitive without the injury.
lol are you serious?
They're cheering for Querrey because they want the USA to win.
Sure the injury may give them more life but it's not like you expect them to say "oh Nole is injured, I'll just stop cheering now" do you?
People tend to cheer more when the feel they have a better chance
